Hello everybody
After a lot of investigations I still having problems to set the clock of my CForce 520 2018.
In the manual they indicate to press the "ADJ" (right side) button short to change the hour and long to change the minutes. I tried it in many ways, but nothing changes. I also tried to do that procedure after disconnecting and reconnecting the battery. For old models it seems there is a button under the seat, but not for this model. Could someone indicate me how to set the clock in this new model?
Thanks a lot!

hold in the left side button until the clock flashes then push the right side butun to the correct hour then push te left side button until muntes flash and push the right side button until right minutes are set then push left side button until nothing flashes.

Atleast on my 520 2017

It worked! Thanks a lot.
Tack, tack, tack!
